Dinosaurs are different

Dinosaurs are different by Aliki explains how the various orders and suborders of dinosaurs were similar and different in structure and appearance. You can learn a lot about dinosaurs by looking at their bones. Some dinosaurs were very small; others were huge. Some had sharp, pointy teeth for eating meat; most plant-eaters had flat, dull teeth. Some dinosaurs' hipbones pointed forward, while other dinosaurs' hipbones pointed backward. There were dinosaurs with bony armor on their backs and others with deadly horns on their heads. Today scientists have divided dinosaurs into separate orders according to their special characteristics.
